Cable Inspection Device

The present disclosure relates to the technical field of cable inspection, and specifically to a cable inspection device.

Power system cables are usually laid in cable trenches. The space inside cable trenches is narrow, the environment is enclosed, and silt accumulates. Furthermore, the cable trenches have long longitudinal distances and narrow cross-sections, while also serving drainage functions. To ensure the safe operation of equipment, periodic inspection of cable trenches is necessary. Because cables within the cable trenches are widely distributed, long in length, exposed to rainwater, in poor environments, and difficult to observe, monitoring every point of the cables is costly and difficult to achieve. If inspection is performed by opening the trench cover plates, this results in high maintenance costs. Therefore, it is difficult to effectively monitor conditions such as temperature of the cables, fire, water accumulation, and animal activity inside the trenches in real time. Once a fault occurs inside a cable trench, handling the fault is usually difficult and time-consuming, seriously threatening and affecting the safe operation of electrical equipment.

In the prior art, automatic inspection apparatuses are usually set up to inspect cables inside cable trenches. When water accumulates in the cable trench, the automatic inspection apparatuses, after wading through water, are prone to malfunction, thereby affecting the cable inspection work.

In view of this, the present disclosure provides a cable inspection device to solve the problem in the existing technology where the automatic inspection apparatuses, after wading through water, are prone to malfunction, thereby affecting the cable inspection work.

The present disclosure provides a cable inspection device, including a main body, a monitoring component, a driving component and a water-wading component. The monitoring component is disposed on the main body, and the monitoring component is adapted to acquire and output a monitoring signal. The driving component is disposed at the bottom of the main body, and the driving component is adapted to be movably connected to a cable. The water-wading component is movably connected to the main body, and the water-wading component has a protection state that drives the driving component away from the cable, and a movement state that drives the driving component to contact the cable.

Beneficial effects: in the present disclosure, the water-wading component is disposed on the cable inspection device. When the cable inspection device inspects to a water accumulation environment in the cable trench, the water-wading component can drive the main body provided with the monitoring component and the driving component away from the water surface, avoiding damage to the monitoring component and the driving component by the accumulated water. The monitoring component can output a monitoring signal at the water accumulation location, so that the staff can timely drain the accumulated water in the cable trench.

In an optional implementation, the water-wading component includes a lifting frame and a float component. The lifting frame is movably connected to the main body. The float component is disposed on the main body, and the float component is movably connected to the lifting frame.

Beneficial effects: in the present disclosure, when the cable inspection device moves to an environment with accumulated water in the cable trench, the float component drives the main body to rise along the lifting frame under the buoyancy force of the accumulated water, leaving the water surface, thereby avoiding damage to the monitoring component and the driving component caused by contact between the main body and the accumulated water. After the accumulated water is drained, the float component drives the main body to descend along the lifting frame under its own gravity, and continues to inspect along the cable.

In an optional implementation, the float component includes a first support frame, a sliding member, a first elastic member, a first pull rope, a float and a second pull rope. The first support frame is disposed on the main body, and a first mounting hole is provided on the first support frame.

The float is connected to an end of the first pull rope away from the sliding member, and the gravity of the float is greater than the elastic force of the first elastic member. One end of the second pull rope is connected to the sliding member, and the other end is connected to the lifting frame.

Beneficial effects: in the present disclosure, the gravity of the float is set to be greater than the elastic force of the first elastic member. During normal operation, the first elastic member is stretched under the gravity of the float, and the sliding member is separated from the driving component. When the cable inspection device operates to a water accumulation environment, the float floats up under the buoyancy force of the accumulated water, and the first elastic member returns to its original state, causing the sliding member to connect with the driving component. The first pull rope is wound around the sliding member, thereby causing the main body to rise along the lifting frame, thus avoiding damage to the monitoring component and the driving component caused by contact between the main body and the accumulated water.

In an optional implementation, the float component further includes a first connecting member and a second connecting member. The first connecting member is connected to the sliding member. The second connecting member is connected to the driving component, in which one of the first connecting member and the second connecting member is provided with a connection portion, and the other one is provided with a connection groove, and the connection portion is movably connected to the connection groove.

Beneficial effects: in the present disclosure, the first connecting member and the second connecting member are movably connected via the connection portion and the connection groove. When the cable inspection device operates to a water-wading environment with accumulated water, the first connecting member and the second connecting member are connected to each other, and the main body is lifted along the lifting frame via the first pull rope to leave the water surface, thereby avoiding damage to the monitoring component and the driving component caused by contact between the main body and the accumulated water.

In an optional implementation, the float component further includes a first sensor. The first sensor is disposed on the sliding member, and the first sensor is in signal connection with the monitoring component.

Beneficial effects: in the present disclosure, when the first sensor detects accumulated water, it transmits a signal to the monitoring component, which then sends it to the staff, facilitating the staff to timely drain the accumulated water in the cable trench, allowing the cable inspection device to continue inspection, while also avoiding the impact of accumulated water on the cables in the cable trench.

In an optional implementation, the driving component includes a driver, a first transmission shaft, a first transmission belt and driving members. The driver is disposed on the main body. The first transmission shaft is rotatably installed on the main body, and the first transmission shaft is movably connected to the water-wading component and the monitoring component. The first transmission belt connects the driver. Two said driving members are disposed at the bottom of the main body and on both sides of the cable, and the driving members are movably connected to the first transmission shaft.

Beneficial effects: in the present disclosure, two driving members are disposed on both sides of the cable. The driving members drive the first transmission shaft to rotate, causing the driving members to move along the outer wall of the cable, thereby enabling the cable inspection device to inspect along the cable.

In an optional implementation, the driving component further includes a guard plate. The guard plate is disposed at the bottom of the main body, the guard plate is provided with a mounting portion, which matches the shape of the cable, and the mounting portion is movably disposed on the cable.

Beneficial effects: in the present disclosure, the guard plate is disposed above the cable. The guard plate matches the shape of the cable. When the cable inspection device moves along the outer wall of the cable, it can serve a guiding and protective role.

In an optional implementation, the driving component further includes a second sensor, in which the second sensor is disposed on the driver and is adapted to detect a travel distance.

Beneficial effects: in the present disclosure, the second sensor is set to output the travel distance and position of the cable inspection device.

The first monitor is rotatably disposed on the main body, and the first monitor is movably connected to the driving component. The second monitor is fixedly disposed on the main body, and the second monitor is in signal connection with the first monitor and the driving component.

Beneficial effects: the first monitor set in the present disclosure can detect the inspection environment and transmit the detection data to the second monitor for recording and storage. The second monitor can also send the information to the monitoring center, so that the staff can timely obtain the inspection information.

In an optional implementation, the monitoring component further includes a second transmission belt and a second transmission shaft. The second transmission belt is movably connected to the driving component and the water-wading component, respectively. The second transmission shaft is rotatably disposed on the main body, one end of the second transmission shaft is connected to the second transmission belt, and the other end is connected to the first monitor.

Beneficial effects: in the present disclosure, when the driving component drives the cable inspection device to inspect along the cable, the second transmission belt and the second transmission shaft drive the first monitor to rotate, so as to monitor and inspect various angles inside the cable trench, improving the inspection effect.

3 5 23 24 21 In the present disclosure, when the driving componentdrives the cable inspection device to inspect along the cable, the second transmission beltand the second transmission shaftdrive the first monitorto rotate, so as to monitor and inspect various angles inside the cable trench, improving the inspection effect.

The working process of the cable inspection device in the present disclosure is as follows:

The driving componentand the monitoring componentare started. The driverdrives the drive gearto rotate, driving the first transmission beltto move. The first transmission beltdrives the bevel gearto rotate. The bevel geardrives the third gearto rotate, thereby driving the drive wheelto move along both sides of the cable, causing the cable inspection device to move and inspect along the cable. At the same time, the second geardrives the second transmission beltto rotate, causing the fourth gearto drive the worm gearto rotate. The worm geardrives the worm wheelto rotate, causing the first monitorto rotate, achieving monitoring in different directions.

The second transmission beltdrives the friction wheelto idle. During the inspection process, when the cable inspection device moves to a water accumulation location, the floatfloats up under the buoyancy force of the accumulated water, causing the first connecting memberand the second connecting memberto engage with each other. As the first connecting memberrotates, the second pull ropeis wound on the first connecting member, thereby lifting the main bodyupward along the lifting frame, avoiding contact between the main bodyand the accumulated water. At the same time, the drive wheelseparates from the cable, and the cable inspection device stops moving and inspecting, sending out information about the water accumulation location. After the staff drains the accumulated water, the floatdescends again under gravity, pulling the first connecting memberto separate from the second connecting member. Then, the drive wheelcontacts the cable, and inspection can continue.

5 5 The cable inspection device in the present disclosure can not only inspect the cableand the environment in the cable trench, but also detect whether there is accumulated water in the cable trench, timely sending a water accumulation signal to facilitate maintenance of the cable trench by the staff, avoiding the impact of accumulated water in the cable trench on the cable.

Although the embodiments of the present disclosure have been described in combination with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present disclosure. Such modifications and variations shall fall within the scope defined by the appended claims.
